HORN FOR TALKING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 759,639, dated May 10, 1904.

Application filed July 21, 1903. Serial No. 166, l49. (No model.)

To all 1072 0771 it may concern:

Be it known that I, HORACE SHEBLE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Horns for Talking-Machines, of which the following is a specification.

My invention consists of an improvement in the construction of horns primarily designed to be connected to the conduit leading from the vibrating diaphragm or sound-box of a talking-machine of any of the well-known forms, the object of the invention being to provide means for damping or preventing the vibrations of the metal of which the horn is composed, which heretofore have ordinarily interfered with the vibration of the column of air within the horn, so as to give a more or less objectionable quality to the music or other sounds reproduced by the machine to which the horn is attached.

A further object of the invention is to provide means whereby the appearance of ahorn of the character above noted may be greatly enhanced, said means being of such a nature as to be durable.

These objects I attain as hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of a horn for use in connection with a talking-machine, being illustrated as provided with a covering according to my invention. Fig. 2 is a sectional elevation of the horn shown in Fig. 1, showing the detail construction of the same.

In horns for the purpose noted it has hitherto been customary to construct them of either polished brass or bronze throughout their entire length or to simply have them polished at their mouth or bell, while covering with black japan or other similar material the body or conical portion. To those accustomed to the use of machines for reproducing sound it is well known that hitherto there has always been present an objectionable metallic note produced by the machine when in operation, due in a great measure to the fact that the vibrating column of air within the horn sets in vibration the metal of the horn itself, which in turn causes vibrations of air, so as to give rise to the objectionable note or tone mentioned. I have found, however, that by covering the body or conical portion of the horn with a layer of cloth, preferably adherent to the horn, the quality of the sound reproductions is greatly improved and that with the entire absence of the objectionable metallic sound heretofore always present.

In the above-mentioned drawings, A is the body or conical portion of a horn formed of metal, as is usually the case, and having at its smaller end a cylindrical nozzle a for attachment to the tube connected to the sound-box containing the vibrating diaphragm of the talking-machine.

a is the hell or mouth of the horn and is held, as customary, to the large end of the body portion A by means of a turned-over edge in engagement with a flange (0 on said body portion.

B is a layer of cloth preferably extending over the entire surface of the body portion A and being held thereon by glue, Varnish, or any other desired material. Not only does this coating of cloth dampen the vibrations of themetal horn, and thereby improve the quality of the sounds reproduced by the machine, but it gives a finished appearance to the body portion of said horn and is itself of such a nature as not to be easily injured or disfigured. This is quite an important feature, as the japan or varnish hitherto used is very easily scratched, with consequent injury to the appear-ance of the horn.

I claim as my invention- 1. As a new article of manufacture, a horn for talking-machines, the same having a substantially conical body portion of relatively stilf sheet metal and having a covering of Woven fabric upon said body portion, said fabric being permanently retained in intimate Contact with the body, substantially as described.

2. As a new article of manufacture, a horn In testimony whereoflhauesignetlmy name for a talking-maelnne, the same including it to this speelfication 1n the presence of two subeonieal body portion and amoutlipiece therescribing Witnesses.

for, said parts being of relatively stifi' sheet HORACE SHEBLE. 5 metal with a covering of cloth glued to the itnesses:

said body portion of the horn, substantially CHAS. SULZNER,

as described. MARIE E. DONIGAN.
